To all whomct may Genom.

-Be it known that I, FRANK ToMAsnma citizen of the United States,residing at Chicago', in the county of Cool( and State of Illinois, haveinvented certain new and useful improvements in Automobile Bump ers, ofwhich the vfollowing is a specification.

My invention relates tobumpers for automobiles, and has ior its objectthe provision of e new and improved bumper consisting of a plurality oi'bars so formed and secured. together as to provide a bumper that isrelatively light in "weight, yet suiiiciently strong torvlthstand therough usage to which automobile appliances of this charin appearance,provide a reiatively buliing surface, and which be manuactured a minimumcost,

The invention has for further objects the vnovel constructions,arrangements and com- {ie-3 ci 2, and illustrating, on a somebinationsof parts hereinafter described and claimed, for carrying out the abovestatedobjects, and such other objects as will appear from th followingdescription of a pre-` yvhatlarger scale, the structural details 'of thecenter portion oi. the bumpero Liire characters of reference designatocorresponding parts in 'the several ligures of the Y Referring' to tbedrawing, my improved bumper is shown as consisting of a relativeiy longouter bar l@ oi; spring metal, a shorter inner bar li. of spring metal,and a reiativeiy wide birding plate i2. The outer spring bar 10 is bentintermediate its ends, as indicated by the reference numerals 13, 13,and the end Vportions are curved inwardly and rearwardiy, as indicatedby numerals 14, 14, and terminate in relatively straight portions i5,15, which normaily at substantially right angles to the front face orthe outer' bar. @be inner bar is, preferably, somewhat shorter than theouter bar 1G, and is provided with a dat face Y acterI are subiected,which will sigbtiy which is secured to the central'pormon oi the outerbar. The ends of the inner bar are bent rearwardly to provide reversecurved portions 16, 16, corresponding in part to the contour of kthecurved portions i4, 1li, oit' the outer bar and terminate in straightportions 17, 17, adapted to besecured to the ends of the outer bar bybolts 18,18. The straight ends 15 and'17 of both spring bars are adaptedto be attached directly, or by means of brackets (not shown) to anautomobile chassis so as' to support the bumper in a horizontal positionacross the iront, or the rear, as 'may be desired, of the automobile.

The buiing plat-e 12 is, preferably, though not necessarily, made ofspring metal and consists of a relatively Wide bar removably secured to4the flat face of the,outer springb'ar near the middle thereof, by bolts19, 19,

ivbich bolts lextend through elongated open-V ings 19a--19a in the innerspring y`vbar 11 and rigidly clamp the boiling plate 12 to the outerspring bar 1G and clamp the said outer and inner spring` bars togetherwith capacity for longitudinal movement of the buer plate and outerspring bar with relation to the inner spring bar. lThe central portionof the boiling plate 12 is cut away 'as indicated by the numeral 20 andthe end portions are reduced in Width, as shown by Y numerals 21, Q1, tosubstantially the same Width as the outer spring bar 10.

With such construction the bufiing plate 12 provides a relatively widebuiiing surface, and thereby minimizes the likelihood of the bumper, inthe event of a collision with another automobile, passing above or belowthe bumper of said other automobile, and at the seme tim@ does notappreoiably increase the Weight or the cost of manufacturing the bumper.

The buiiing plate 12 may be readily removed from the spring bar 10 forthe purpose oi repairs, or if it be provided with a a polished ornickel-plated surface, to polish or re-niclrel Wit-.hout removing .theentire bumper. i
